The Attempt at a Solution

This is throwing me off because there are basically 2 tetrahedral. So, that is what I did. I drew a tetrahedral VSEPR structure and I connected another one to it upside down.
Is that wrong? I wish I could draw it somehow to show you. On here. I said this molecule is non-polar. Symmetric so everything dies.

Looks like you have a molecule of ethane. Do you know about carbon chain molecules yet?

No. They just gave me like a couple practice problems. I have a question. I have a little trouble with determining the dipole moment sometimes. What is a safe way to determine it? I know if the molecule is symmetric and all X;s are the same then it is non polar.
